Description
When a device under test needs more headroom than 30 V, the Keysight DP5744AH DC power supply is the next step in the group. It delivers up to 40 V and 85 A, or 3,400 W, from a three-phase 380/480 VAC input. Lost in HCM lists it for rental and sale in Vietnam.
Trading current for voltage in the Keysight DP5744AH DC power supply
Compare it with the smaller models in the same series. The DP5742 gives 20 V at 170 A, and the DP5743 gives 30 V at 112 A. The Keysight DP5744AH DC power supply tops out at 40 V and 85 A. So the voltage ceiling rises while the current ceiling falls, and the power stays near 3.4 kW.

Settings and speed
The 20 mV programming accuracy is coarser than the 10 mV and 15 mV of the two smaller models. However, a 40 V range makes that step a small fraction of the span. The output responds in 30 ms, so allow a short wait before each reading. For example, a ramp test should pause after every step.
Slew rate is adjustable, and arbitrary waveforms let a script draw the output curve. Meanwhile, built-in measurement reads voltage and current for each step.
Where the 40 V rail earns its place
The listing points to automated production and qualification racks, power-device and converter validation, automotive and industrial electronics testing, and laboratory development. GPIB, LAN, USB and LXI connect it to a controller, while overvoltage and overcurrent protection guard the part.
The AH input at your site
The AH version takes three-phase 380/480 VAC. The DP5744AL takes three-phase 200/240 VAC, and the DP5744AS takes single-phase 200/240 VAC. Confirm the feed with an electrician first.

DP5744AH questions
How does it differ from the DP5743AH?
It gives 40 V and 85 A instead of 30 V and 112 A.
Can the output be shaped by a script?
Yes, through adjustable slew rate and arbitrary waveform generation.
